HYBRID PHOTOELECTRIC SMOKE DETECTOR AND SMOKE DETECTION METHOD USING LIGHT SCATTERING AND PHOTOSENSITIVE EFFECT

摘要

The present invention relates to a hybrid photoelectric smoke detection device and a smoke detection method using a light scattering and light extinction method, and more particularly, a frame having an internal space configured as a dark room so that smoke particles can be introduced; A light emitting device formed on one side of the inside of the frame and emitting light to detect smoke particles in the dark room; A light receiving element formed on one side of the inside of the frame to detect light from the light emitting element and convert the light into a voltage signal; And a light detector formed outside the frame to receive a voltage signal detected by the light-receiving element and to transmit a fire occurrence signal. It is about.
